I originally voted this question as a duplicate. However, the OP is correct in that the proposed duplicate does not address the specific case of sous vide. Here, I attempt to help in that regard.
The definitive source for the answer to your question is Douglas Baldwin. From the information you've supplied, it is difficult to make any safety claims. However, you can compare your product, and your practice, to the points made by Baldwin.
First, sous vide (true sous vide...in a vacuum) can indeed extend shelf life...
IF certain hurdles are cleared.
FIRST, your product is cooked to the pasteurization stage. It is hard to tell how thick your chicken breasts are from the photos. Baldwin has tables that cross reference thickness, temperature, and times so that you can achieve pasteurization. You'll have to compare your practice to this chart to see if you met the threshold. So, once sealed in a vacuum, the first hurdle is to pasteurize your product.
THEN, your product must be cooled as quickly as possible for long term storage. This usually means in an ice bath, then immediately refrigerating or freezing. The method is called "cook-chill." Baldwin cautions, however that "The danger with cook-chill is that pasteurizing does not reduce pathogenic spores to a safe level. If the food is not chilled rapidly enough or is refrigerated for too long, then pathogenic spores can outgrow and multiply to dangerous levels."
Cook-chill, done correctly, greatly reduces the risk from listeria, and spore forming pathogens. However, he goes on to write:
"spores of Clostridium botulinum, C. perfringens, and B. cereus can all survive the mild heat treatment of pasteurization. Therefore, after rapid chilling, the food must either be frozen or held at
below 36.5°F (2.5°C) for up to 90 days,
below 38°F (3.3°C) for less than 31 days,
below 41°F (5°C) for less than 10 days, or
below 44.5°F (7°C) for less than 5 days
to prevent spores of non-proteolytic C. botulinum from outgrowing and producing deadly neurotoxin (Gould, 1999; Peck, 1997)."
