White dots on iPas Pro Screen

FYI,

This is NOT called light “bleeding”.

An internal source light “bleed” is caused when the light actually spills out and away through cracks/crevices in a device's/object's structure.

In such a case as any tablet, phone or computer light spillng out the the edges or openings of a device.

This effect can happen with any flat screen monitor/TV that uses backlighting to assist in lighting up all the screen’s internal pixels.

The term “bleed” in these types of instances come vaguely from the art/printing world where a color “bleed” is where color spills out to the edge of the paper/canvas medium's boundaries to fill a seection of the art medium edge.

The correct term for the effect shown on this iPad's screen can be called/described as “spotlights/spotlighting ”, “stage lights/stage lighting or stage “curtain light/curtain lighting” and this is an issue with the iPad’s backlight source.

These terms describe what the effect actually looks like, which does, in fact, look like spot lights, stage lights or stage curtain lights

That is Light Bleed, which the screen protector would not have influenced at all.

Schedule an appointment at your Apple Store Genius and show it to Apple.

You're welcome and good luck.

OK and good to know. Either way, the OP needs to take the iPad to their nearest Apple Store Genius Bar.
