Even ignoring chroma, video compressed at streaming bitrates is nowhere near the nyquist limit for a given resolution.
In addition, YouTube generally encodes 4k at like 5-6x the bitrate of their 1080p encodes (codec for codec), rather than merely 3-4x higher which would be closer to the same quality per pixel.
So yeah, YouTube's 4k is better on a 1080p screen than their 1080p stream.
