Replace the shine and detail with a classic rubber mask, silicon makeup, and matte brown body paint in exactly the same head and body shape, stick them at a side table in Quarks circa S6 of DS9, and I challenge you to notice anything amiss. I think that is true for how they looked s2 Discovery with the hair and normal skulls I stead of the elongated Crystal Skull shaped look we got in s1.
For me, having them look like TNG Klingons doesn’t even solve the problem because ENT had implied that shouldn’t happen until the TOS movie era. They could have rendered explicit the implication that not every Klingon was infected by the virus, but that still doesn’t support making the Klingons look how they did in s1 DIS.
