Looks like that huh?….but nope. This is what my PE looks when my lights are full power. My PE isn’t nearly as good when the lights are out. Weird….but true

Is this important to have? I just started with SPS but mine only show exceptional PE when I first turn on lights in the morning.

Polyp extension varies a great deal by species of SPS with some smooth skin, deep water acropora showing none at all.
I think good PE is generally considered a sign of good health for most tenuis and millipora. That said, I get very little PE but have great growth and color in my tenuis. So I am kind of curious to hear more thoughts on this question.
The only thing that corals NEED to use their polyps for gas exchange. Too much can be a sign of issues like ammonia or other toxins and too little might be a sign of stress and the coral not producing energy from the zoox. I would be worried if there was no PE ever or so much that it looks like the polyps are going to bail out. The polyps are out more at night to exchange gas when the lights are not on the zoox are not active. Acros can also extend the polyps to try and catch some food, but nobody know if what they can catch in our systems is worth anything compared to the risk that some crab or fish is going to take a bite.
In the end, PE means nearly nothing. Hairy acros don't grow any faster than the same species in another tank with less PE... or slower. I would just look for changes... if yoursare normally hairy and now not, then investigate, or vice versa. I would look to color and growth as a better sign of health.
In super short, PE is fools gold.

Figuring out the hobby one coral at a time.
If I didn't let my wife talk me into yet another pygmy angel, I would have PE for days.
I'm not kidding either. Lost my african flame back to jumping about a year ago, about 3 weeks later my acros all got super hairy and stayed that way. Fast forward about 8 months and my wife talked me into a lemon peel angel, nearly overnight I lost all PE.
Polyps do come out at night, but during the day, 0 PE.
