Flash,
It is not the quality of the Bino's that is the core reason for the result you are experiencing.
Bino's act by splitting the available light source in two to share between the user's two eyes. The amount of light to each eye is effectively halved, thus dimming the apparent brightness registered by each eye.
Our brains do not add the two together when processing the final image. So our final perception of the image is correspondingly dimmer.
The dimmer the original light source, the more noticable the dimming effect. Conversely as the brightness of the original light source increases the effect appears to disappear as the brain adjusts for high brightness levels. Hence your good experience with your earlier with daylight viewing.
This dimming will be apparent with your TV85 on all but the brightest objects as the scope is not gathering enough light. Larger scopes will deliver the extra light needed to overcome this dimming. Hence your memory of your earlier experience with the larger LX90 8".
I trust this makes sense.
Cheers
Steve.
