Such gravity lens observational studies can be instrumental for establishing a limitation on the precision of testing General Relativity in the weak-field regime and on the two gravity constants (the Newtonian and cosmological ones) as described in Gurzadyan and Stepanian (Eur Phys J C 78:632 2018). Namely, we predict a critical value for the involved weak-field parameter $$\\gamma _{cr}=0.998$$ <math><mrow><msub><mi>\u03b3</mi><mrow><mi>cr</mi></mrow></msub><mo>=</mo><mn>0.998</mn></mrow></math>  (for $$M=1.5\\,\\,10^{11}\\, M_{\\odot }$$ <math><mrow><mi>M</mi><mo>=</mo><mn>1.5</mn><mspace width=\"0.166667em\"></mspace><mspace width=\"0.166667em\"></mspace><msup><mn>10</mn><mn>11</mn></msup><mspace width=\"0.166667em\"></mspace><msub><mi>M</mi><mo>\u2299</mo></msub></mrow></math>  lens mass and $$r=2\\, kpc$$ <math><mrow><mi>r</mi><mo>=</mo><mn>2</mn><mspace width=\"0.166667em\"></mspace><mi>k</mi><mi>p</mi><mi>c</mi></mrow></math>  light impact distance), which remarkably does not depend on any hypothetical variable but is determined only by well measured quantities. If the critical parameter $$\\gamma _{cr}$$ <math><msub><mi>\u03b3</mi><mrow><mi>cr</mi></mrow></msub></math>  will be established at future observations, this will mark the first discrepancy with General Relativity of the conventional weak-field Newtonian limit, directly linked to the nature of the dark sector of the Universe."
