To understand the restriction here is how Hybrid maps them:

The currently known and supported:

• GRAY8, GRAY16, GRAYH, GRAYS
  
• YUV420P8, YUV422P8, YUV444P8, YUV410P8, YUV411P8, YUV440P8,
  
• YUV420P9, YUV422P9, YUV444P9, YUV420P10, YUV422P10, YUV444P10,
  
• YUV420P16, YUV422P16, YUV444P16, YUV444PH, YUV444PS,
  
• RGB24, RGB27, RGB30, RGB32, RGB48, RGBH, RGBS
  
• COMPATBGR32, COMPATYUY2
  

The groups:

• ALLGRAYX: GRAY8, GRAY16
  
• ALLGRAYFLOAT: GRAYH, GRAYS
  
• ALLGRAY: ALLGRAYX, ALLGRAYFLOAT
  
• ALLYUV8: YUV420P8, YUV422P8, YUV444P8, YUV410P8, YUV411P8, YUV440P8
  
• ALLYUV9: YUV420P9, YUV422P9, YUV444P9
  
• ALLYUV10: YUV420P10, YUV422P10, YUV444P10
  
• ALLYUV16: YUV420P16, YUV422P16, YUV444P16
  
• ALLYUVX: ALLYUV8, ALLYUV9, ALLYUV10, ALLYUV16
  
• ALLYUVFLOAT: YUV444PH, YUV444PS
  
• ALLYUV: ALLYUVX, ALLYUVFLOAT
  
• ALLRGBX: RGB24, RGB27, RGB30, VSRGB32, RGB48
  
• ALLRGBFLOAT: RGBH, RGBS
  
• ALLRGB: ALLRGBX, ALLRGBFLOAT, COMPATBGR32
  
• ALLCOMPAT: COMPATBGR32, COMPATYUY2
  
• ALL: ALLGRAY, ALLYUV, ALLRGB, ALLCOMPAT
  
• FULLYUV: YUV440P8, YUV444P8, YUV444P9, YUV444P10, YUV444P16
  

There are probably discrepancies to the actual capabilities of the filter due to mistakes or changes in the filters I missed or simply that there was no documentation when about the filters capabilities when I added support for it.
In example Hybrid might restrict a filter that doesn't need to be restricted or doesn't restrict the filter enough or too much.
-> if you find a mistake let me know and I'll fix it.
