How important is an LCD screen on your streamer?

Maybe glance at it across the room to check if it’s powered on. Streamer(s) turn off after a power outage; something we get here more than a few times a year. iPad or phone runs roon/streamers.

I thought it would be an unnecessary feature at best, add to the cost for sure, and possibly have a negative noise effect on on sound quality at worst.  I operate my system remotely from my iPad (usually) or my iPhone or laptop (sometimes).

Not at all, makes noise. My DAC  has no LED let alone a screen, my transport has an LED and it is in the off position.

Not at all. My streamers allow me to turn it off. Which I do. 

I have always thought a screen on a streamer is redundant given that a tablet is usually the control surface for any streamer.   Or a phone 

As an owner of a Bluesound Vault 2i and an Aurender N200  my advice would be to listen to a few different streamers and see which has a better user feel and sound to you regardless of whether it has a screen or not.   I know a lot of people look past Innuos because there is no screen but they are steadfast in the belief that it causes noise.  Their new Statement has no screen, $21,000.    That says something.    

My Dad bought an Eversolo A6 , because it had a screen.  I warned him that they are relatively new to the  audio streaming space  and to buy a Bluesound.

He ignored my advice and now has a box with multiple issues . Instead of fixing issues , they create more with each update.   

I can't tell you how many times I have brought it over to my system to confirm it's the streamer and not his gear or LAN or wifi.   At least 5 or 6.   I have put my streamer in his system just to be 100% sure.  That's not worth having a touchscreen.  

I would suggest the Bluesound Icon or Aurender A1000 depending on budget if no screen is a deal breaker.  Both stable with good support.   Aurender is in another league with respect to support.
