Aha. I found the issue. The problem happens only with images that were uploaded BEFORE new theme were applied. Exact size weren’t generated and thus not shown.

However, I still don’t understand why julia-nikitina-portfolio-Marta112-Large-425×283.jpg wasn’t selected.

Thanks for the reply @bhargavbhandari90. That’s what I do. Unfortunately, this only adds width, height attributes to the img tag but doesn’t scale the image.

Here is my code:
echo get_the_post_thumbnail( get_the_ID(), $image_size );

and this is what it produces:
<img width="355" height="237" src="https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large.jpg" class="attachment-nakamura-port-list-landscape size-nakamura-port-list-landscape wp-post-image" alt="Portfolio-stylistka-julia-nikitina-Marta12" srcset="https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large.jpg 1620w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-300x200.jpg 300w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-768x512.jpg 768w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-1024x683.jpg 1024w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-1200x800.jpg 1200w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-425x283.jpg 425w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-650x433.jpg 650w, https://nikitina.pl/wp-content/uploads/2016/12/julia-nikitina-portfolio-Marta112-Large-1300x867.jpg 1300w" sizes="(max-width: 355px) 100vw, 355px">

As you can see the src tag references full-res post featured image.

I can confirm that the seller refunded my purchase.
