A positive print film, for making positives from masked neg, looks more less like that when exposed in camera with no filter and processed as negative and slide.
AFAIK internegs are masked.
You mentioned some vericolor. Vericolor Slide (5072) which I often shot in camera, seems more contrasty than your film when developed either in C41 and E6 (i did both), but it can be matter of scan, exposure and process. VS while being a c41 film gives dense, slide black in E6.
The only other print positive film I have experience with is ORWO PC7, which behaves somewhat similar but its rather unlikely that's the one.
