Thanks for the file. It is really like I wrote. Your content stream has 
this at Root/Pages/Kids/[0]/Contents/[1]  :

0 Tw
0 Tc
0 0 0 rg
0 0 0 RG

Your output profile at   Root/OutputIntents/[0]/DestOutputProfile/N has 
a value of 4. "rg" and "RG" are rgb commands. N=4 means 4 colors, 
typically CMYK.  (However the profile itself is RGB. Change the N to 3 
and it works fine with us and with PDF Tools)

Re OutputIntents : "(Optional; PDF 1.4) An array of output intent 
dictionaries that shall specify the colour characteristics of output 
devices on which the document might be rendered (see 14.11.5, "Output 
Intents")."

and

"Output intents (PDF 1.4) provide a means for matching the colour 
characteristics of a PDF document with those of a target output device 
or production environment in which the document will be printed. The 
optional OutputIntents entry in the document catalogue (see 7.7.2, 
“Document Catalog”) holds an array of output intent dictionaries, each 
describing the colour reproduction characteristics of a possible output 
device or production condition. The contents of these dictionaries may 
vary for different devices and conditions"




It is of course surprising that Adobe would claim the file is OK. Their 
PDF/A check is by Callas, and they're among the best in the PDF/A 
business. Maybe they ignore the "N" value?
