Difference between high quality and Lossless in path display?

In some of the community topics I see the path with the description Lossless. In my case all lossless situations are indicated as High Quality. What is the reason for this?

Because you are using the DSP volume control.

Is not lossless when you do this kind of digital processing.

OK thanks! However the comfort factor is too big to give up on this. And I think the sound is still good on low volumes.
