The afore mentioned smearing, (I have called it out hundreds of times on various forums), is also called the plastic look or worm look. Yes, it's real depending on the raw converter used, and IMO it's also present in the jpgs taken in camera especially if medium to hard sharpening is added.
However same smearing, is gone with the following software (IMO),
Capture One, Vr 9 and up, Silkypix Studio Pro Vr 7 and up, ON1 raw (latest version), Iridient Developer (all versions), LR (only in the latest versions).
Note LR can still bring out the plastic look at times, but it's much better than it used to be to my eyes, so Adobe seems to have definitely improved on the X-T2 and X-Pro 2 conversions.
You can also see the same detail smearing in the older X-T1, X-Pro 2, net any of the Fuji's that were 16MP.
As to the flare into the sun, (really not too surprised by this), every camera I have used from Nikon to Phase One has some form of flare (usually destructive)
when shot directly into the sun or when at an angle. The magenta color is very common.
There were early reports of a checker board or grid like look to the magenta flare when the X-T2 first shipped, but I have not seen it. And I shoot a lot into the sun.
I would recommend lensrentals.com try it and see what you think for yourself.
