To the left of the screen and the iPad in the height position, there are two strange lines that are fixed in this place when moving the iPad in any way and using any application. I do not know the reason for their presence, although the iPad is new and has not fallen or been damaged
iPad Pro, iPadOS 15
A reliable method to confirm a screen or other hardware fault is to take a screenshot when the fault is evident - and then review the captured screenshot image...
When reviewed, if the lines are not present in the screenshot image, then you have demonstrated that you have a hardware fault that, sooner or later, may become sufficiently severe that repair or replacement of the iPad are the only options. If the lines are visible in the screenshot, the something other than hardware will be the cause.
Note: When reviewing the image, rotating the iPad screen orientation by 90°, from Portrait to Landscape, will ensure that the image does not coincide with screen defects if present.

If the screenshot does not replicate what you can see only screen, you have a screen hardware fault. The only resolution is repair of your iPad.
With you iPad being new, you’ll have a warranty upon which to make a claim with your retailer.
In the screenshot, the lines do not appear, but I took a picture with another device to make it clear to you
