Looks good. I've always used a solid light blue, like the sky on a clear day, or a decent size cardboard.

You could do the boring thing and open a new page in a word processor on your computer or tablet, focus on infinity and shoot that. Remember to set the aperture to the smallest opening available to really see any contamination on the sensor surface.

Just make sure you clean your screen first. Specks, flecks, oil contamination, and bunnies seem to really show on a light blue backer of some kind. Probably green, tan, yellow, pink, or any solid light color would do.
I've had my share of specks and bunnies. My D750 developed several on my Gettysburg trip, and had to erase them in Affinity and clean the sensor. Easy enough task, but those wipes are kinda pricey!

Second important thing is to use the aperture with the highest value available on your lens (f22 and more), as on wide open apertures, the spots may be softened out.
With the above you should be able to already identify the spots on the cameras screen if you zoom in.
If you export the pictures to a computer with a photoprocessing software you may additionally increase the contrast to the max (it is not about viewing the picture in its best processing ) in the software to identify spots, if the aperture was f16 and more.

Finding spots before/after cleaning is to take a picture of something with as less detail (ie it being as uniform) as possible (prefereably the sky (blue or grey), but also a white wall, etc.) shooting a picture which shows details may hide the spots in the image.

do not shoot over F/4.8 and if have to will do now.
