How much dirt is too much dirt

in regards to power conditioning?  I’ve always found better sound when turning off the tv, I thought because of the distraction (mental thing). Recent purchase of an EMI meter (Trifield EM100) shows the tv with 15 - 20 mv added noise to a base of 25 to 50 mv line noise, time of day dependent.  I sit here, close my eyes, flip the tv on and off, and hear real music tv off, painfully disrupted audio joy, tv on.  Then contemplate noise figures.  Specifically a post where a claimed drop of 200 something to 78 mv made their day.  I’ve never seen posted what is an excellent, good or poor number.  Anyone?  My real question being, will a line conditioner lower my power line dirt enough to be worthwhile?

I didn't expect a definitive answer but you never know until you ask, right?   

I did find that my garage lighting is horrendously noisy.  It's cheap, bright 100W total LED strip lighting with a whopping 1,300 mv noise at the source, and a good percentage of that showing up at my gear.   

So garage lights off.  

Reducing line noise from 70 mv to 50mv (tv off) is beneficial.  70 mv is where the strength bar starts flickering a second bar.  50 mv and below seems sonically ok for now.
