Should Sigma make a 30 MP per layer full-frame Foveon instead of 20 MP per layer?

About 40MP to match 8K 16:9 screen resolution

Some might argue that 8K must be at least 8192 pixels wide, but the common standard is 7680 pixels, so 7680x5120 (39.32... MP) resolution is needed for a 3:2 sensor and then a 16:9 crop gives you 7680x4320 resolution.

Foveon sensors record all primary color channels in full resolution, so no oversample room is needed. A bayer color filtered sensor would need a lot more resolution to cover a 8K 16:9 screen properly.

Dynamic range is another thing which is a weak side of a Foveon technology. Landscape photos need that or anything where strong light like the sun is visible. It needs to be solved.
