The expression diṭṭhisampanna denotes one who has seen the truth of the Dhamma, beginning with the sotāpanna. See the closing paragraph of SN 12:27, etc.

list various qualities of the diṭṭhisampanna, e.g., being incapable of regarding any formation as permanent, etc., being incapable of parricide and matricide, etc. Spk glosses abhisametāvino: “for one who abides having made the breakthrough to the noble truths by means of wisdom” (paññāya ariyasaccāni abhisametvā ṭhitassa). On abhisamaya, see n. 13:
[Note 13 of Nidana Vagga] As a technical term, abhisamaya appears in the Nikāyas in two main contexts:
(i) As signifying the initial breakthrough to the Dhamma, dhammābhisamaya , it is identical with the obtaining of the vision of the Dhamma (dhammacakkhupaṭilābha), and thus with the attainment of stream-entry; see SN 13:1 [current sutta] (II 134,4-5).
(ii) As signifying the complete breaking through of conceit (sammā mānābhisamaya) it is equivalent to the attainment of arahantship; see SN 36:5 [http://www.accesstoinsight.org/tipitaka/sn/sn36/sn36.005.nypo.html](IV 207,14-15) and I, v. 725c.
(iii) A third suttanta use is to denote the Buddha’s discovery of the Dhamma, as here and in the verb form abhisameti at SN 12:20 [http://dhammawheel.com/viewtopic.php?f=25&t=11574] below. In the commentaries abhisamaya is synonymous with paṭivedha, penetration, both terms being used interchangeably to characterize the four functions of the supramundane path; see Vism 689-91 (Ppn 22:92-97).
Spk: What is the suffering that has been destroyed? That which might have arisen if the first path had not been developed. The suffering that might have arisen in the plane of misery during the next seven existences, and that which might have arisen anywhere at all beginning with the eighth rebirth—all that has been destroyed.
BB: Both dhammābhisamaya and dhammacakkhupaṭilābha signify the attainment of stream-entry. On the benefit of stream-entry, see Dhp 178.

Sole dominion over the earth,
going to heaven,
lordship over all worlds:
the fruit of stream-entry excels them.
