Pixbim Video Colorizer AI: how accurate is it? Please read description first!

Many people including myself likes to upscale and colorize old BW films.
I use an app called Pixbim Video Colorizer AI wich I think gives a good result.
But...how accurate is it?
I used a random video from Chrete, converted to BW and then cororized it with PVC AI to see how accurate it actually is.
I think it does pretty well, but clear blue, deep red and yellow "spot" colors on details are missing....wich is natural because how should a software know the colors of specific details?
This can be fixed using PSD Neural Filters AI if we know what color it should be (flags, lipstick and so on..
But shown here is what comes out from Pixbim unedited.
