What's wrong with 4K?
Sorry, just seeing this.
Yeah, everything is too small requiring scaling/interpolation.
Even in Photoshop, where I do a lot of e-commerce product work, 100% mag is too small to comfortably do detailed retouching on. I found myself working at 200% mag for a similar view.
It's not that one can't work around this stuff, I just didn't find it a "feature". Would much prefer panel uniformity, correct gamma, neutral grayscale, etc, over "lots of tiny", as Andrew said.
It's kinda like being told there's this great new feature of your newspaper: they can now fit twice as much print on every page, all you gotta do is use these awesome magnifier glasses to read it. Not really as awesome as it's made out to be.
That said, that's just my experience for my needs. Totally get if people working globally on huge images, etc, feel otherwise. For them it may be a great feature; but again probably somewhere down the line of uniformity, gamma, grayscale, etc.
