| Re: DVE (Digital Video Essentials)
I've just been going over DVE (PAL version) with an HDMI analyser (because I don't trust stuff either), and I can report that all the 100% and 75% colour bars, and all the grey fields, are within 1 unit of the correct numbers when output by my players with picture controls set to standard - so less than 0.5% error.
There is a complication in that SDTV and HDTV use different RGB<->YCbCr matrices - this means that an sort of SD->HD upscaler has to perform a fairly subtle transformation on the YCbCr values on the disc, if it's set to output YCbCr over HDMI. Some devices may get this wrong, leading to somewhat dippy colours. My kit gets it right, thank goodness - the transformed HDTV YCbCr values are correctly transformed.
There's a more minor issue in that SDTV and HDTV also use a slightly different colour of green. But that's a very subtle issue, and upscaling kit doesn't generally attempt to correct for that, but displays sometimes do. That means you may get very slightly different colours from direct SD input to a TV and upscaled SD input to a TV, if the TV uses different primaries for SD and HD input. That effect would be very subtle though.
I don't think any of this applies to you though - you may just be comparing 75% and 100% (intensity) colour bars. That's not a saturation difference, it's a brightness difference. DVE has both, tucked away in the reference section - see if you can find the 100% version, and compare that to Avia. (I forget whether AVI has 100% or 75%).
