That is true. However, 4K resolution is 3840x2160 (7,516,800 pixels). When looking at Dolphin resolutions, the base resolution is 640x528.
So 6x puts you at 3840x3168 (12,165120 pixels). Looking at the edges you get multiples of 1x1.46 (+0x+.46), and looking at pixels gives 1.6183908 times number of pixels.
At 7x puts you at 4480x3696 (16,558,080 pixels). Looking at the edges you get multiples of 1.16x1.71(+.16x-.29), and looking at pixels gives 2.20280971 times number of pixels.
Neither are a true integer multiple of a 4K screen, but going by these numbers, wouldn't 7x be better at scaling?
(my logic could be totally flawed though, but this was my thought process on scaling)
