So this file means that:

0x21 11 21 00

First component is Horizontal sampling factor 2, Vertical sampling factor 1,
Second component is Horizontal sampling factor 1, Vertical sampling factor 1,
Third component is Horizontal sampling factor 2, Vertical sampling factor 1.
No 4th component.

So there is no vertical sampling? But Cb is preserved? Interesting.

BTW, if component ids are 'Y','C','c' it is PhotoYCC, and if it is 'Y','C','c','A' it is PhotoYCCA :) Just as used in Kodak Photo CD. As you can see Ci is one byte actually ;)

From mediainfo:

0A3  Nf - Number of image components in frame: 3 (0x03)
0A4  Component - 1 (0x1) - 2 (0x2) - 1 (0x1) (3 bytes)
0A4   Ci - Component identifier:            1 (0x01)
0A5   Hi - Horizontal sampling factor:      2 (0x2) - (4 bits)
0A5   Vi - Vertical sampling factor:        1 (0x1) - (4 bits)
0A6   Tqi - Quantization table destination selector: 0 (0x00)
0A7  Component - 2 (0x2) - 1 (0x1) - 1 (0x1) (3 bytes)
0A7   Ci - Component identifier:            2 (0x02)
0A8   Hi - Horizontal sampling factor:      1 (0x1) - (4 bits)

It is not bit perfect with photoshop though, with a very interesting pattern, every other line is broken.

BTW, there are unsupported yet samples in this comment: https://forum.doom9.org/showthread.php?p=1678985#post1678985

0x41211100
0x11412100
0x11311100

And there is patch for support of 0x41212100 https://patchwork.ffmpeg.org/project/ffmpeg/patch/20180618201930.84734-1-derek.buitenhuis@gmail.com/
