Help! Is it possible to output video from DSLR to PC without losing quality?

My current setup is a Canon T6i, and im sending the image to my PC through a HDMI and a capture card to be recorded using OBS. I tried all the best setting I could find, but the video quality is visibly inferior to the one I can get with the camera alone.
Here's a comparison of a frame from OBS and a frame from the camera's card. Same angle, same light, same everything: https://imgur.com/a/YkXQOlB

Is there anyway I can use this DSLR to stream my podcast in good quality?
