The fading will vary depending on things sitting on it...but it all gets there (the terminal colour) in the end. The sun 'swings' in the sky (from east to west; down to up to down again; winter - summer - winter). These swings mean different angles will be 'hit' at different times of the day, and the year. These swings 'even out' over the years.
And light 'bounces'. UV rays will bounce off of glossy things, off walls and then back onto floors. That means the floor will have subtle variations (NOT striations) from left to right and from close to the windows to the furthest wall. These variations are SOOOOOO subtle, you HAVE to leave something on the floor for 6 months or so to reveal how much the floor has faded around it.
And remember: the brain will convince the eye that it is seeing something 'normal'. An example:
A darker floor that is in a dark corner = normal. A light floor in a well lit area = normal. That means a floor that has NO fading (down a dark hallway) will look NORMAL so long as it is in a 'naturally dark' setting. A HEAVILY faded cork floor sitting directly in front of a large window = normal looking.
As for furniture shadows, they even out. Yes you will be a little surprised at first (the first time you move the sofa) you will get used to it by week two. After 12 months, the fade will be almost unnoticeable. Almost.
For these reasons, I always recommend leaving the area rugs off the floor for the first 6 months (or at least through the first FULL summer). Once the floor has been given a chance to mute its colour, you can then place the area rugs. That means the next time you move the furniture, the difference between the rug shadow and the faded floor will be less intense. Again, you will take a bit of time to get used to it...and then you will forget it was ever an issue.
Tasmanian Burl is a fantastic COLOUR. The COLOUR in Tasmanian Burl is a STAIN. The stain will remain 'live' for 2 years or so...and then the fade will take hold and you will lose almost all the colour you paid for.
Logan is the MOST EXPENSIVE cork finish on the market today. Where Tasmanian Burl costs money because it has a STAIN (stain adds cost), the Logan adds value because of how EXPENSIVE the cork veneer is (large pieces of cork are EXPENSIVE and RARE). So the two come close to the same price...but for two different reasons.
Here's how I liken the two products:
Tasmanian Burl = Swirly Zebra Stripes under a pretty stain that fades quickly
Logan = Natural Travertine looking cork that FADES to natural LIMESTONE colours!!!
Logan looks a bit like a dry laid stone pathway. It is TRULY stunning. It starts life in the Travertine Peach/Gold tones and then fades down to the LIMESTONE cream colours. I love BOTH the look of Travertine AND Limestone so I love the look of Logan either way.
If you love the depth of the Tasmanian Burl, I think you will be disappointed to see it fade out heavily. I've faded out this colour myself. It turns to a grayish beige that is not what most people want when they purchase an Gunstock brown cork floor.
If you like the movement of the 'burl' but want the easy life of the Logan, I would look at the Desert Arable in the 10mm. It is SOOOOO cool in a larger pattern. It really looks like etched sandstone (imagine the striations of the Grand Canyon). Desert Arable might be 10mm, but you can bump up the cork quantity by adding 3mm cork underlay for LESS than the price of the Tasmanian Burl.
Just my 2 cents. Considering I used to sell ALL of these products, I can help as much as you need me to. First things first: order your samples and then make some of your decisions after you have them in your hand.
