Is my photo presentation in Adobe Premiere Pro really in 4K?

I would like to ask you if my photos are at least in 4K when - I put 6 000*4 000 pixels photo (or more) into one of the applications such as Mirror Lab and Glitch Lab (photo editing softwares available on Google play) and it is exported in 4242*2828 pixels. The question is these photos are really 4K when they are sent externally to my tablet, which doesn't have 4K photo nor video camera, the maximum resolution of a photo on my tablet is 6,1 mpx. I hope it is really in 4K. These photos are not taken on my tablet, they are sent there externally, that's why I hope there might be a chance they are in 4K resolution.
I also put these pictures I made there in Adobe Premiere Pro and I tried to play them in 1/4 quality and 1/8 quality to ensure myself it is really 1/4 and 1/8 of 4K. I am absolutely not sure. How can I persuade myself of the true quality of my photo presentation? I would like to export my photo presentation in 4K to MP4, but I don't want to lie, nor deceive myself and others, if it is not. Minimally it is in 2K, Quad HD.
Thank you for your answer.

Set up a 4K which is 3840x2160 sequence and export as such.

I don't know Mirror Lab or Glitch Lab, but they might already have reduced the image quality, at least they reduced the resolution.

What is the extension of these images.

4K is 3840 X 2160 pixels.

If your media is 4k, your sequence is 4K, and your export settings are 4K, then you will have 4K.

If your display is not 4K, then it will either rescale it or crop it, depending upon the device and its settings.

Ann and Peru Bob perfectly illustrate a nomenclature issue ...

 

As "4K" is, in a strictly technical term, several things.

 

There's 4k DCI, which is 4096x2160.

There's UHD, which is also often called 4k, and is 3840x2160.

 

And at least three cameras I know of do "4k" with their own specific width, running around 4100 plus a few pixels.

 

But as to your question, if your sequence framesize is X, and you use Set to Framesize to move your files onto that framesize, the resolution will be that of the framesize of the sequence.

 

Whatever you set for that framesize.
