I agree with Havasman, only you can make that cost benefit calculation.
TV always had excellent coatings, and TV products were expensive, so they almost always were well cared for.
I've had good luck with used TV eyepieces, and am not driven to extract an extra percent of so of throughput.
Certain types of observing will call for that extra drop of performance, so only you and your wallet can decide. For me, I have a few other items higher on my list. For now.
I have a range of smoothie Naglers and they suit my budget and eyes.
If I hit the stock market jackpot I would go for all new NT6 and Ethos without a regret or second thought. Virtually every TV product has made me happy.
I will leave it to the retinal sensitivity experts, but it is my understanding that a percent or two of light reduction may not be readily perceptible except under limited circumstances. And I have no doubt certain, limited, observations may call for it.
