Not sure where you've seen a picture with the rear camera screen in the mirror with these. Again, I have not seen a single picture that shows the screen in the mirror. I've been in a 2018 limited Cadenza and both breeds of the 2019 K900, and neither of them offer the camera screen in the mirror as I recall.
As to the standout, I agree, the side panels of the second generation were a little bland, and the front and rear didn't stand out quite as much. But I've seen them on the road, they are sharp looking cars. I never liked the quad LED fogs on the Limited, for 2 reasons, it looks odd, and also they only look right straight on, if you're one lane over it seems that their direction or shroud are cutting off the main beams from the farthest away light, and it looks like it's either off or aimed very poorly.
But this 2020 sneak peek, the front end looks so sharp and standout, it kills the front end of both of the previous models. I also HATED the white running light tube in the first gen. That thing was never bright enough to run as a DRL and really just looks awful on any other color then white. the Tube just looks like an after thought. Also the black grill on the first gen from any distance looks like a vacant hole. I got the Chrome OEM grill and it makes the car stand out, but without it, I don't think black grill has any prowess other then when you're standing under 10 feet from the car.
