That's a significant problem. It definitely means your calibration is wrong.

Then it's time to try a new lab. (The exact same photos)

Just on the website in the usual way. https://www.damiensymonds.net/index.html

Well, just rearrange your panels like I taught you in the Layers & Masks Class.

The most common reason for this inconsistency is the lab. Did you mistakenly allow the lab to make adjustments to your files when you sent them for print?

Gosh!

You don't have to save it straight away. But it doesn't hurt. Save (by hitting Ctrl S) frequently as you're editing, so you keep your PSD file up-to-date (in case you have a computer crash or a power outage). But don't save multiple PSD files of course. Only the one master PSD file.

I urge you to re-read the very last module of the Bridge Class. This is spelled out very clearly.

This is why you must NEVER CROP YOUR MASTER FILE. https://www.damiensymonds.net/2011/09/cropping-tutorial.html

Crikey, I don't know, I'm so sorry.

Maybe you need to do an entire reset on the screen?

This sounds quite normal. See if your lab provides a soft-proofing profile. https://www.damiensymonds.net/2010/03/bit-about-soft-proofing.html

Page 26 seems to give some indication of circumstances when colour adjustments aren't available?

Hi Rachael, is it all reds and oranges, or only the richer ones?

Right. And make sure your focal length and everything else remain exactly the same. No. Whites must be white, no matter what.

So would you say that the old lights show the backdrop colour better? It looks like you misunderstood my instructions. I wanted your camera to remain in exactly the same spot, and the tripod bearing the sheet to move.

Awesome, thanks.

Interesting. I'd be incredibly interested to see you put the WB sheet on a tripod, and take a series of photos with the sheet standing progressively further away from the camera.

Great. That's my understanding too. It's just because of the nature of indoor light. It changes over a very short distance. This is perfectly normal.

Different distances might help, but you'll never know which distances are going to work or not I'm saying lost cause.

Well, you'd probably try both Wide LED and GB-LED.

Darn. I'm so sorry, I've got nothing

Thanks. It's nasty. First, try the moire brush in ACR.

@CarmenRM PLEASE dive into your Raw Class! Your membership time has almost run out.

No, you're missing the point. Your options haven't disappeared.
