--- Comment #2 from Danny <[email protected]> ---
Can confirm this bug on the 5.3.0beta1. 

Either bug 99723 is not fixed (but I think it is, the difference is just that
that bug was fixed by looking at recompressing jpeg files only), or this was
not a dupe after all.

How to reproduce:
1) Create a single slide with one inserted png image.
2) Export to pdf with 60% lossy compression 
3) Export to another pdf with lossless compression.
4) Observe that file sizes are identical
5) Compare images in the pdf:
$pdfimages -list test2.pdf 
page   num  type   width height color comp bpc  enc interp  object ID x-ppi
y-ppi size ratio
--------------------------------------------------------------------------------------------
   1     0 image    1152   591  rgb     3   8  image  no         4  0   141  
141 24.0K 1.2%

$ pdfimages -list test1.pdf 
page   num  type   width height color comp bpc  enc interp  object ID x-ppi
y-ppi size ratio
--------------------------------------------------------------------------------------------
   1     0 image    1152   591  rgb     3   8  image  no         4  0   141  
141 24.0K 1.2%
